Abstract: Two kinds of low cost Hall displacement sensor are exploited and researched for the bearingless slice motor. Basic operating principle is introduced and analyzed. Matching circuit is designed to combine with Hall element and experiments are performed under the dynamic and static situation. The experiment proved that the displacement sensor has upper sensing precision and it is comparatively inosculate with theory analysis. The applied result proved that the displacement sensor has good performance and it is suitable for the bearingless slice motor.
